The Arylpyrrole Series
The initial two leads have the general structure:
These compounds are currently under study by the Todd lab at the University of Sydney and the Medicines for Malaria Venture, Geneva. As an open source project, anyone may participate:
Electronic Lab Notebooks
Compounds are commercially-available
Series was listed as one of the most promising leads from TCAMS set (though lacking aryl F)
A number of these compounds and intermediates are available for biological testing from Todd group by request.
